PTFE-Lined Pneumatic Ball Valve
The PTFE-Lined Pneumatic Ball Valve is a corrosion-resistant valve designed for automated flow control in aggressive chemical environments, featuring a PTFE (polytetrafluoroethylene) lining to withstand acids, alkalis, and solvents, combined with a pneumatic actuator for rapid switching or precise regulation. Ideal for industries like chemical processing, pharmaceuticals, and wastewater treatment.
